An integral loop flushing shuttle spool is used to separate system A and system B pressures.
System delta pressure will cause the shuttle spool to shift, allowing the low side system pressure to flow
to the loop flushing relief valve.

Warning
Unintended vehicle or machine movement hazard.
Excessive motor loop flushing flow may result in the inability to build required system pressure in some
conditions. Maintain correct charge pressure under all conditions of operation to maintain pump control
performance in hydrostatic systems.
